The Euro MotoElectrics EnDuraSpark Electronic Ignition is an electronic hall effect trigger and electronic ignition advance module that replaces under-performing BMW Ignition points, condenser, mechanical advance unit and on later models, the electronic ignition control unit and bean can trigger unit.
This ignition replaces the ignition systems on all 1970-1995 BMW Airhead motorcycles. It is configurable for both single-plugged and dual-plugged engines. The EnDuraSpark ignition system is the last improvement ever needed on an Airhead ignition!

This EnDuraLast Electronic Ignition kit is designed for 1970-1980 BMW points–based ignition motorcycles which have been upgraded to the EnDuraLast Charging System.This kit is not designed for use with BMW motorcycles using the stock Bosch alternator or later BMW motorcycles with existing factory electronic ignitions.Different kits for these models are available from Euro MotoElectrics. Please refer to Part # EDL-BOIGN for retrofitment on Bosch Alternator frame.

This kit is designed for both stock single-plugged engines and engines which have been modified to add a second spark plug to each cylinder, “dual-plugged” engines.

The kit can be used on BMW Airheads with exposed points under the front engine cover:

·All /5s (1969-1973 R50/5, R60/5 and R75/5)

·All /6s (1973-1976 R60/6, R75/6, R90/6 and R90S)

·Some /7s (all R60/7, all R75/7, R80/7 and R100/7 up to 1978)

·R100S, R100T, R100RS, R100RT up to 1978

and BMW 1979-1980 Airheads with points in the "bean can":

·1979 R100S,

·1979-1980 R80/7, R100S, R100T, R100RS, R100RT

·All R45, R65 up to 1980

·1980 R80G/S, R100, R100CS

This kit does not work with /2 or any other pre /5 BMW model.

BMW models after 1981 had electronic ignition with high energy spark coils.

Euro MotoElectrics has a different kit for these models.

Component Compatibility

Spark Plug Compatibility

The EnDuraLast Electronic ignition should be used with stock spark plugs, stock ignition wires, and stock ignition caps.For spark plugs, this means non-resistor plugs.Bosch has phased out their original non-resistor W5DC, W6DC and W7DC spark plugs and replaced them with WR5DC, WR6DC and WR7DC plugs, respectively. These are resistor plugs not compatible for this application.Currently, Bosch non-resistor spark plugs can only be purchased at BMW motorcycle dealers.

Spark Plug Cap Compatibility

The EnDuraLast Electronic ignition is compatible with the OEM stock 1K Bosch, 1.2K Beru, and 5K Bosch spark plug caps that originally came on the motorcycle.It is also compatible with any 1K or 5K aftermarket spark plug caps such as the NGK LB01FP, LB05FP or LB05EP.

Ignition Wire Compatibility

The EnDuraLast Electronic ignition is compatible with the OEM stock ignition wires that were originally outfitted on BMW Airheads.These are Hypalon covered, stranded copper core, non-resistor ignition wires with a resistance of about 2 ohms per foot.The ignition is also compatible with Hypalon or silicon insulated stranded copper aftermarket wires, such as that manufactured by Accel, Belden, and Packard.

It is important that copper core wires are used, not the carbon powder center ones normally sold at auto parts stores.

Coil Compatibility

The EnDuraLast Electronic ignition is compatible with all stock BMW ignition coils used on models using points and condensers.Specifically, the EnDuraLast can be used with ignition coils that have a primary resistance seen by the electronics between 2 -3 ohms.Since both stock Airheads and dual-plugged Airheads use two coils wired in series, each of these coils needs a primary resistance of 1 to 1.5 ohms.

The EME ignition is NOT compatible with conventional electronic ignition coils, which typically have a primary resistance of around .7 ohms.These coils will fry the EnDuraLast ignition.The older black Bosch coils and the newer electronic black Bosch coils look almost the same – except the electronic ignition coils (which can’t be used) have a small yellow lightning icon on them.

Battery CompatibilityThe EnDuraLast ignition system is NOT compatible with lithium iron batteries as supplied by Shorai.

The optimal replacement coils available for use with the EnDuraLast Electronic Ignition are the Bosch 6V 1.5 ohm “Super” coils, part # BO-Coil6Vx2 available from Euro MotoElectrics.

FAQ - Frequently Asked Questions

This kit Part # EDL-IGN is for fitment over the EnDuraLast Alternator frame.

For fitment over original Bosch Alternator frame, please refer to Part # EDL-BOIGN .

1.Can the EnDuraLast Ignition be used with a…

·BMW /2?

·R65?

·Moto Guzzi or other non-BMW motorcycle

·BMW Oilhead, Hexhead, or K-bike?

·“bean can” bike?

·BMW with factory electronic ignition?

·Omega alternator?

No.The model year must be 1970-1980.

Yes, for model years up to 1980.

No.

No.

Some, only years 1979-1980.

No.Euro MotoElectrics has a slightly differentversion for these models.

No.

2.Can the stock ignition system be left on the bike?

Yes.

3.Is it easy to switch back to the stock ignition?

Yes, five minutes.

4.Can I use my existing coils?

Yes, if stock.

5.Can I use a “hotter” coil?

No.The primary resistance of the two coils in seriesmust be 2-3 ohms.

6.Can I use my existing spark plugs?

Yes.

7.Is a condenser used?

No.

8.Can carburetors be synchronized by shorting the spark plug caps?

Yes, but the caps must always be grounded to something.

9.Does it hurt to leave the ignition key on with the engine not running?

No.

10.Can I change the amount of electronic ignition `advance?

No.You may select 20° or 26°

11.Can I change the initial timing?

Not really.The initial timing or the final timing can be set, but not both independently since the total advance range between them is fixed.Timing should be adjusted to make the advanced timing perfect, letting the initial timing fall where it may, generally 8°.

12.Can I change the maximum advance value?

Yes, it can be setanywhere.

13.Can I adjust the ignition curves?

No.

14.What is the dwell?

The system has a variable dwell. The system provides a constant 4ms dwell time independent of RPM.

This is the normal sound of the EnduraLast alternator creating an electromagnetic field at all RPMs.

20.When the removing the flywheel, the crankshaft must be blocked from moving forward.This prevents the thrust washer on the crank inside the engine from slipping off its locating pins.How do you block the crankshaft when the EnDuraLast Ignition has been added to the front of the crank?

Simply back out the rotor bolt a half an inch and replace the front cover.Gently tighten down on the cover bolts.The cover will push on the rotor bolt, keeping the crankshaft from moving forward.

21.Can the EnDuraLast ignition be used with a battery loss system on a race bike, i.e., without an alternator?

Yes, it is a very good ignition for racing applications.You will need a battery designed for total loss systems, i.e., physically vibration tolerant and capable of multiple deep cycles without losing capacity.Voltage needs to remain above 11.5 volts as the battery discharges until it is almost dead.Two commonly used motorcycle racing batteries are:

The dual-plugged ignition curve should be selected with the dip switches in the EnDuraLast black box for racing applications even if the motor is not dual plugged.This is because the dual-plugged ignition curve ends 600 RPM sooner, 3000 RPM vs 3800 RPM.
